SESSION VARIABLES (PHP Version 5.2.4)

cdub1885 · February 12, 2008

I'm setting up a user input form with session variables. The values get dropped from

one page to another and the first page is haveing trouble resetting the variable.

As you can see I'm using an array $v[]

????

Are my arrays set correctly. Do I have to set a variable in php.ini?

I do not want to turn of globals.

<?php
// paqe 1  = index.php
include 'db.php';
session_start();
$v = array();
$_SESSION[$v];	
$v[0] = "Recipe Name";          $v[1]= "Catagory";      $v[2]= "Source";       $v[3]= "Special Materials"; $v[4]= "Ingredients";   $v[5]= "Instructions";
echo "varray debug <br / >";
print_r($v);

?>
<html> 
<meta http-equiv="Refresh" Content = "1; url = textinput.php">
<head><title> index </title></head>
<body></body> 
</html>
end of page 1

start of page 2
<?php
// page 2 = textinput.php"
session_start();
$inputs = array();
for ($i = 0; $i < 6; $i++){
	$inputs[$i] = $_SESSION[$v[$i]];
}
echo "inputs array debug <br / >";
print_r($inputs);
echo "<br />";

echo "v array debug <br / >";
print_r($inputs);
echo "<br />";


?>

$sql = "insert into teachers values (";
    		$sql .= $data_sql;
    		$sql .= ");";	

	$result = @ mysql_query ($sql,$connection)
		or showerror();

	mysql_close();

echo "<h1>Your inputs have been submitted.<br>";
echo "<h3>sql code: $sql";

You save the empty array $v into your seession. You need to store your data in the $v array and then save it to the session.

Hey thanks. I tired that to no avail. What is the syntax to save $v to the session.

I used: $_SISSION[$v];

Do I have to destroy the session?

Actually, didn't even see that. To save a value into the session array is just like any other associative array.

$_SESSION['v'] = $v;
